Background documentationSolution: Time-Based Reduction for SAP SCM


This migration solution is applicable to the migration of data from an SAP SCM system.

With this migration solution, you can migrate the following types of data:

  • Transactional Data: SAP TDMS uses the data slice date you specify to transfer all transactional data created on and after this date from the sender system to the receiver system. The transactional data consists of the following data:

    • Enterprise Warehouse Management (EWM) Data:SAP TDMS transfers EWM data based on the specified data slice date.

    • liveCache Data: SAP TDMS transfers liveCache data based on the specified data slice data and the planning version.

    • Other Transactional Data: SAP TDMS transfers all other transactional data completely.

    Note Note

    To ensure data consistency in the receiver client for the specified data slice date, SAP TDMS transfers additional transactional data that is business-relevant.

    End of the note.
  • Master Data and Customizing Data: SAP TDMS transfers the complete set of master data and Customizing data regardless of the data slice date you specified.


You can carry out data scrambling in the sender system after selecting the data and before transferring the data to the receiver system.

SAP TDMS copies the data selected for transfer to a data cluster and scrambles the cluster data before transfer.



This migration solution includes the following phases:

  • Package Settings

    In this phase, you make certain technical settings such as assigning logical system names in the receiver system, excluding user-related data from data transfer, specifying scrambling rules, selecting additional customer-created tables for transfer and so on.

  • System Analysis

    You execute background activities that prepare the migration objects for transfer and generate programs for data deletion.

    You can also change the deletion method to delete data in the receiver system.

    You confirm your migration settings so that they become effective for data transfer.

  • Data Transfer

    In this phase, you execute the final checks before data transfer to ensure that no significant changes have taken place in the repository of the sender system while your SAP TDMS project is running.

    SAP TDMS deletes the existing data from the receiver client and starts the data transfer, including the transfer of data from the liveCache. You can lock the users in the receiver system so that no changes take place during data deletion and data transfer.

    Further, in the SCM systems, the Order Document Management (ODM) and Time Series Data Management (TSDM) frameworks generate tables. The names of the system-generated tables could differ in the different systems. Hence, SAP TDMS for SAP SCM enables the appropriate mapping of tables between the sender system and the receiver system.

  • Post-Transfer Processing

    In this phase, SAP TDMS makes a few post-transfer settings in the receiver system such as adjustment of number ranges and adjustment of Business Workplace tables.

    If you had set a lock on users in the receiver system during data deletion, you can unlock the users now.

    You can additionally clear the temporary tables filled during the data migration in all participating systems.
